摘　　要：为消除钢丝绳抖动累加对落地式提升装置运行状态的影响,通过分析落地式多绳摩擦提升原理及控制要求,提出了基于PLC的矿井提升机变频调速和防抖动运行的技术方案。该方案利用分布式I/O采集到的钢丝绳张力、制动闸瓦磨损、油压等特征信号,干预提升电机的运载状态,消除抖动累加,以实现远程监控,确保提升稳定。In order to reduce the rope shaking effect in the mine hoist, the working principle and basic control request of floored multi-ropefriction hoisting system has been introduced, the frequency conversion and shaking scheme has been developed based on PLC. With the use of collecting rope tension, wear of brake pawl, hydraulic pressure from distribution I/O, the mine hoist can be controlled,and reduce the rope shaking, ensure the stability of the mine hoist and realize the monitoring.
